Jose is an exceptional founding engineer with proven 0→1 product experience, strong full-stack capabilities (FastAPI, Next.js, Node.js), and deep expertise in real-time systems and multi-channel delivery—exactly what OneSignal needs. His background scaling omni-channel messaging (voice, SMS, WhatsApp, web) at Addie directly mirrors OneSignal's personalized messaging platform. The main gap is no demonstrated experience with push notifications, SMS gateways, or email delivery systems that are core to OneSignal's product.
Hook: You've built real-time multi-channel messaging at scale (10+ countries, 99.9% reliability); OneSignal is looking for a founding technical leader to own the next generation of their omni-channel platform.
Missing: Push notification systems, SMS/email delivery expertise, Customer data platform (CDP) experience, Analytics and attribution systems
